Which cell develops into a plasma cell?
Stem cells develop into plasma cells and B cells also turn into plasma cells. Plasma cells have been exposed to an antigen and then produces and secretes antibodies.
Who is responsible for antibody production?
Naiive B cells are lymphocytes that have not yet been exposed to antigen. Once it can identify a particular antigen, it will undergo production of antibodies and become a mature B cell. Mature B cells are split into two categories: plasma B cells and memory B cells. Plasma B cells will continue to produce large amounts of antibodies. Memory B cells are stored so that the next time you encounter the same antigen, it can start producing antibodies much quicker because it remembered from the previous encounter.
Enhance immune responses to subsequent exposures to an antigen to which the body has already been exposed are know as?
memory responses
What is hypotonic cell?
Hypotonic cells are cells that have been exposed to hypotonic solutions. These solutions cause cells to plumb as they fill with the solution.
What is the difference between hepatitis B surface and hepatitis b antigen?
When your body is introduced to the Hepatitis B virus, the virus is considered the antigen (the surface antigen)and this should trigger your immune system to develop antibody against this antigen to destroy it. Most people do develop Hep B surface antibody when infected with the Hep B virus. Some people do not develop the antibodyand go on to have only circulating Hep B surface antigen - which means they are a carrier and can continue to have the virus and infection. For the majority of the population that develop the Hep B surface antibody, this conveys immunity to the virus for life.
What is the difference between soluble and particulate antigen?
A soluble antigen is a viral antigen that remains after the virus has been removed. A particulate antigen is produced by particles such as dust and germs.
What is the condition called of soldiers exposed to wet and cold conditions?
I have been called "atmospheric".
What is characteristic of all cancers?
all the petri dishes with cancer cells have been exposed to tobacco smoke.
What is the mode of action of cromolyn sodium?
It prevents mast cells from bursting and spilling their contents after they have been in contact with an antigen. It's taken daily to prevent asthma attacks.
What is a magma chamber called after the conduit has solidified and been exposed by erosion?
batholith
What is a volcanic conduit called after the conduit has solidified and been exposed by erosion?
Volcanic neck
My children are Rh negative. Their father and I think we are Rh positive. Is this possible?
Individuals either have, or do not have, the Rhesus factor (or Rh D antigen) on the surface of their red blood cells. This is usually indicated by 'RhD positive' (does have the RhD antigen) or 'RhD negative' (does not have the antigen) suffix to the ABO blood type. Unlike the ABO antigens, the only ways antibodies are developed against the Rh factor are through placental sensitization or translation. That is, if a person who is RhD-negative has never been exposed to the RhD antigen, they do not possess the RhD antibody.[1] The 'RhD-' suffix is often shortened to 'D pos'/'D neg', 'RhD pos'/RhD neg', or +/-. The latter is generally not preferred in research or medical situations, because it can be altered or obscured accidentally. There may be prenatal danger to the fetus when a pregnant woman is RhD-negative and the biological father is RhD-positive.
